We’ve discussed numerous methods for making a cup from a glass bottle, but I don’t recall seeing anyone use the neck before. Brookelynn from CRAFT has us covered, though, with this guitar slide made from a wine bottle:
One interesting historical example of upcycled crafting is the bottleneck guitar– or as it is now widely known, slide guitar. The unique resonant sound of slide guitar was originally formed by playing with a glass bottleneck over one finger and running the slide up and down the strings. While the materials for making slides have evolved, bottles are still a popular choice of material. We were given one, and as it has been used over the years, the piece has developed some lovely scratches that give the glass beautiful character. Slideplayer.com has two great ideas for making your own, including a “Burning Twine” method that sounds really cool (and drunkenly dangerous).
